Fabric certification is one of the most frequently asked questions by B2B buyers on Alibaba.com. Two certifications dominate the apparel industry: OEKO-TEX STANDARD 100 and GOTS (Global Organic Textile Standard). Understanding the difference is critical for matching your product to the right buyer segment.
OEKO-TEX STANDARD 100 vs. GOTS: Key Differences
| Feature | OEKO-TEX STANDARD 100 | GOTS (Global Organic Textile Standard) |
|---|
| Primary Focus | Finished product chemical safety—tests for 1,000+ harmful substances | Organic fiber content + entire supply chain ethics (environmental + social) |
| Organic Requirement | Not required—can certify polyester, nylon, conventional cotton | Minimum 70% organic fibers for 'made with organic' label; 95%+ for 'organic' label |
| Testing Scope | Laboratory testing of final product for harmful chemicals (REACH, CPSIA compliant) | On-site audits of all stages: farming, spinning, weaving, dyeing, manufacturing, packaging |
| Certification Process | 6-step process: application, testing, certification, surveillance | 7-step process: application, on-site audit, review, certification, annual renewal, transaction certificates |
| Cost Range (Annual) | USD 800-2,000 depending on product categories | USD 1,200-3,000 plus audit fees |
| Validity Period | 12 months, requires annual renewal | 12 months, requires annual audit renewal |
| Best For | Mass market buyers prioritizing chemical safety compliance | Premium/eco-conscious buyers requiring organic + ethical supply chain |
| Market Recognition | Globally recognized, especially in EU and North America | Gold standard for organic textiles, growing demand in EU and US premium segments |

[2][3]OEKO-TEX STANDARD 100 focuses exclusively on chemical safety of the finished product. It tests for over 1,000 harmful substances including formaldehyde, heavy metals, pesticides, and allergens. The certification has four product classes:
- Class I: Baby products (strictest limits)
- Class II: Products with direct skin contact (shirts, blouses, underwear)
- Class III: Products without direct skin contact (jackets, coats)
- Class IV: Home textiles (curtains, tablecloths)
For women's blouses, Class II is the relevant standard. OEKO-TEX is widely recognized by EU and North American buyers as proof of chemical safety compliance, particularly for REACH (EU) and CPSIA (US) regulations [2].
GOTS v8.0 (effective March 2026) is significantly more comprehensive. It requires:
- Minimum 70% certified organic fibers for 'made with organic' labeling
- Minimum 95% certified organic fibers for 'organic' labeling
- Certification of all supply chain stages: farming, ginning, spinning, weaving/knitting, wet processing (dyeing, printing, finishing), manufacturing, packaging, labeling, and trading
- Environmental criteria: wastewater treatment, chemical input restrictions (no toxic heavy metals, formaldehyde, aromatic solvents, GMOs)
- Social criteria: ILO labor standards, no child labor, safe working conditions, living wages
- Annual on-site audits by accredited certification bodies
- Transaction Certificates (TCs) for each shipment to verify organic content throughout the supply chain [3]
GOTS is the gold standard for organic textiles and is increasingly required by premium buyers in the EU and US, particularly for brands marketing sustainability credentials.
"OEKO-TEX tests the finished product for 1000+ chemicals and can be applied to polyester. GOTS requires organic cotton AND ethical supply chain practices. They're fundamentally different certifications serving different buyer needs." [4]

"For GOTS, the label must be on the actual product with a license number you can verify. The Transaction Certificate is the gold standard for proving organic content through the supply chain." [4]

Which certification should you choose?
- OEKO-TEX is ideal for: mass market buyers, price-sensitive segments, buyers prioritizing chemical safety compliance without organic requirements, faster time-to-market (4-6 weeks vs. 3-6 months for GOTS)
- GOTS is ideal for: premium/eco-conscious brands, EU buyers with strict sustainability mandates, buyers requiring full supply chain transparency, brands marketing 'organic' or 'sustainable' positioning
Important: Some buyers require both certifications. GOTS certification automatically includes OEKO-TEX-level chemical testing, but OEKO-TEX does not cover organic or social criteria. For maximum market access, consider pursuing OEKO-TEX first, then upgrading to GOTS as your buyer base matures.
